As soon as the new version is out I would like to do a set of predictions on the Ethereum ecosystem with a time range of 6-12 month.
When will Caspar be deployed?
When will Mist be released?
When will we have a first "SPV"-like light client that runs on a phone?
What will be the cost in USD for a simple send Ether transaction (so bet is on gasprice*ETH/USD)
What DAPP is most often used (interacting transactions)
What is the market-cap of the most valuable 5 tokens on Ethereum?
